In the grouped data, the total minutes recorded for each match were calculated and the results were summarized under the minute_count variable. This summary table was then sorted by the number of minutes and arranged for a detailed analysis. In this way, the data for each match was made easier to compare based on minute records.

The blue dots on the graph are below or above the red bars, indicating
that the predicted Draw probabilities (the values provided by the
bookmaker) are lower or higher than the observed Draw probabilities
(empirical P(tie)). If the blue dots are above the red bars, the Draw
probability given by the bookmaker tends to be lower than the actual
data. In this case, betting on Draw can be profitable in the long run,
because the bookmaker gives a lower probability, while the actual
probability is higher. However, there are also cases where the blue dots
are below the red bars. This indicates that the Draw probability given
by the bookmaker is higher than the actual probability, and in such a
case, betting on Draw may not be profitable in the long run. Such
analyses provide an important tool for identifying opportunities in
betting strategies. The lower number of blue dots at the top in the
second half suggests that the Draw odds were more consistent and
predictable. This could mean that the bookmaker’s predictions were more
accurate in the second half and that the outcome of the match was less
uncertain than in the first half. This consistency could have caused the
blue dots to be less likely to be at the top of the red columns.

TASK 2 The code filters out matches that scored after the 90th minute and received a red card before the 10th minute. First, it looks at the differences in the number of goals before and after the 90th minute and identifies matches that show these differences. It then also excludes matches that resulted in early red cards and removes these matches from the match_data_special data frame. As a result, matches that meet certain criteria are removed from the data set and the number of excluded matches is calculated.

TASK 3 Before starting the analysis, I looked at the correlations between the variables and those with a correlation of over 85% to get a general overview.We see a 1 or -1 correlation between some variables (such as Ball Possession % - home and Ball Possession % - away). Since such variables are directly related to each other, I decided not to give importance to this high difficulty in the analysis.

We eliminated some features w/ high correlation during our analysis. Also eliminating extraordinary events helped us to have higher accuracy levels. Additionally, our second half accuracy is reasonable higher (0.74) than our first half accuracy (0.62). Possible reasons for the higher accuracy in the second half than the first half could be that the second half is generally more dynamic and predictable, team strategies become more apparent, and the tempo of the match increases. Additionally, irregularities in the dataset and some features becoming more significant in the second half may have helped the model make more accurate predictions. Changes in teams’ playing style and strategies may also affect this difference.
